About this food

About Peanut butter: Legumes and nuts are typically high in both phosphorus and potassium, so they need care. Plant phosphorus absorbs at a lower rate (30-50%), so the real load is smaller than the numbers suggest. As a Legumes & Nuts item, its role in a kidney diet depends mainly on mineral content.

Nutrient insight

The most striking number here is potassium (37%). For patients on potassium restriction, portion size and leaching are the two levers that matter for foods like Peanut butter.
